With filming set to kick off next week, the final pieces of the casting puzzle are being put into place for Rian Johnson's ambitious sci-fi flick "Looper."

Jeff Daniels, Piper Perabo and Noah Segan (a regular Johnson player having appeared in "Brick" and "The Brothers Bloom") have joined the cast that includes Joseph Gordon-Levitt, Bruce Willis, Emily Blunt, Paul Dano and Xu Qing. The story follows “a killer who works for the mob of the future. He, along with other so-called Loopers, dispose of people sent from the future. When he recognizes one victim as his future self, he hesitates, letting the man escape.” Gordon-Levitt and Willis, of course, play the two versions of the protagonist with Dano as a fellow Looper, Blunt in an unnamed role while Qing is set to portray the wife of Willis’ character. No word yet on the parts for the latest trio of thesps joining the cast.

"Primer" director Shane Carruth is behind camera handling visual effects work for the film that is set in a world “sixty years from now [where] China is the leading superpower and time travel has been invented.” It all sounds wickedly exciting and we can't wait.

No word yet on release dates but we're not expecting this one to hit until 2012. [Variety]
